DESCRIPTION OF THE EMBODIMENTS

Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.

FIG. 1 is a perspective view of an electronic device according to an embodiment of the disclosure. Referring to FIG. 1, an electronic device 50 according to the embodiment is, for example, a notebook computer and includes a first body 52, a second body 54 and at least one hinge module 100 (two hinge modules are shown). The first body 52 and the second body 54 are, for example, the host and screen of a notebook computer respectively and are pivoted to each other by the hinge module 100.

FIG. 2 is a perspective view of the hinge module of FIG. 1. FIG. 3 is an exploded view of the hinge module of FIG. 1. Referring to FIGS. 2 and 3, the hinge module 100 according to the embodiment includes a first bracket 110, a second bracket 120, a pivot assembly 130 and a pressing component 140. The first bracket 110 and the second bracket 120 are connected to the first body 52 and the second body 54 shown in FIG. 1 respectively. The first bracket 110 and the second bracket 120 are pivoted to each other by the pivot assembly 130. The first bracket 110 includes at least one first sliding slot 110a (two first sliding slots are shown in FIG. 3), and the second bracket 120 includes at least one second sliding slot 120a (a second sliding slot is shown in FIGS. 2 and 3 each). The pivot assembly 130 includes a first sliding portion 132 and a second sliding portion 134. The first sliding portion 132 is, for example, a rod and is slidably disposed in the first sliding slot 110a, and the second sliding portion 134 is, for example, a rod and is slidably disposed in the second sliding slot 120a. The pressing component 140 is, for example, a shrapnel and is connected to the first bracket 110 and the first sliding portion 132.

FIGS. 4A to 4C illustrate that the first bracket and the second bracket of FIG. 2 rotate relative to each other. When the first bracket 110 and the second bracket 120 rotate relative to each other, as shown in FIGS. 4A to 4C, the first sliding portion 132 and the second sliding portion 134 slide along the first sliding slot 110a and the second sliding slot 120a, and the hinge module 100 generates a torsional force by continuously pressing the first sliding portion 132 by the pressing component 140. Under the configuration, different pressing forces can be applied to the first sliding portion 132 through different positions of the pressing component 140 in the moving path of the first sliding portion 132, such that the torsional force provided by the hinge module 100 is not a constant value and the effects of both the convenience of operation and structural stability are achieved. The details are presented below.

The hinge module 100 according to the embodiment can include an adjusting structure connected to the pressing component 140. The pressing component 140 presses the first sliding portion 132 by the adjusting structure. Specifically, the adjusting structure is, for example, a lock assembly 150 that locks an end of the pressing component 140 on the first bracket 110 to allow the pressing component 140 to press the first sliding portion 132 by a locking force of the lock assembly 150. The lock assembly 150, for example, provides the locking force along a locking direction D that is perpendicular to an extending direction of the first sliding slot 110a such that the pressing component 140 generates the pressing force applied to the first sliding portion 132.

FIG. 5 is a partial sectional view of the hinge module of FIG. 4A. FIG. 6 is a partial sectional view of the hinge module of FIG. 4C. As shown in FIGS. 5 and 6, an end of the pressing component 140 (a left end of the pressing component 140 in FIGS. 5 and 6) is pressed by the lock assembly 150. Therefore, the closer the end of the pressing component 140 (the left end of the pressing component 140 in FIGS. 5 and 6) it is, the shorter the distance between the pressing component 140 and a bottom wall of the first sliding slot 110a becomes. Further, the larger the pressing force applied to the first sliding portion 132 by the pressing component 140 becomes, the larger the generated torsional force becomes.

Specifically, the first sliding portion 132 is adapted to slide from a first position (the position shown in FIGS. 4A and 5) in the first sliding slot 110a to a second position (the position shown in FIGS. 4C and 6) in the first sliding slot 110a with the first bracket 110 and the second bracket 120 unfolded relative to each other, wherein the second position is located between the lock assembly 150 and the first position. That is, when the first bracket 110 and the second bracket 120 are shut, as shown in FIG. 4A, the first sliding portion 132 is located in a position far away from the lock assembly 150. The larger distance dl is provided between the pressing component 140 in this position and the bottom wall of the first sliding slot 110a. At this time, as the lock assembly 150 applies a smaller pressing force to the first sliding portion 132 via the pressing component 140, the hinge module 100 generates smaller torsional force. When the first bracket 110 and the second bracket 120 operates from being shut as shown in FIG. 4A to being opened as shown in FIG. 4C, the first sliding portion 132 is becoming closer to the pivot assembly 150, and the smaller distance d2 is provided between the pressing component 140 in this position and the bottom wall of the first sliding slot 110a. At this time, as the pressing force applied to the first sliding portion 132 by the lock assembly 150 via the pressing component 140 gradually increases, the torsional force of the hinge module 100 increases.

Accordingly, in a case where the hinge module 100 shown in FIG. 4A generates smaller torsional force, the user may unfold the second body 54 (shown in FIG. 1) and the second bracket 120 relative to the first body 52 (shown in FIG. 1) and the first bracket 110 easily. Moreover, during the process that the second bracket 120 is unfolded relative to the first bracket 110, the torsional force of the hinge module 100 gradually increases such that the second body 54 can be prevented from vibrating unexpectedly. Thus, the effects of both the convenience of operation and structural stability are achievable.

The lock assembly 150 according to the embodiment includes a stud 152, a plurality of elastic washers 154 and a nut 156. The stud 152 is placed into a locking hole 110b (shown in FIG. 3) of the first bracket 110 and a locking hole 140a (shown in FIG. 3) of the pressing component 140. The elastic washers 154 are inserted into the stud 152, and the nut 156 is threaded fully on the stud 152 to press the pressing component 140 by the elastic washers 154.

FIG. 7 illustrates that the nut of FIG. 6 is driven downward. In the present embodiment, by driving the nut 156 downward more tightly, as shown in FIG. 7, the locking force of the lock assembly 150 can be adjusted to become larger, and in this way the distance d2 shown in FIG. 6 between the pressing component 140 and the bottom wall of the first sliding slot 110a shrinks to distance d3 shown in FIG. 7 to change the torsional force of the hinge module 100 to become larger. By making the adjustment, the torsional force of the hinge module 100 can be corrected to make the second body 54 more user-friendly when the user opens up or shuts the second body 54. In other embodiments, the lock assembly 150 can come in other appropriate forms, and the locking force of the lock assembly 150 is adjustable by other proper structures and ways. The disclosure is not limited thereto.

Below are the details of the structure and connecting way of the pivot assembly 130 according to the embodiment of the disclosure. The pivot assembly 130 according to the embodiment includes at least one first connecting rod 130a (two first connecting rods are shown in FIG. 3), at least one second connecting rod 130b (two second connecting rods are shown in FIG. 3), a first shaft 130c, a second shaft 130d and a third shaft 130f. The first connecting rod 130a is pivoted to the second bracket 120 by the first shaft 130c, the second connecting rod 130b is pivoted to the first bracket 110 by the second shaft 130d, and the first connecting rod 130a and the second connecting rod 130b are pivoted to each other by the third shaft 130f. A pivot axial direction of the first connecting rod 130a and the second connecting rod 130b, a pivot axial direction of the first connecting rod 130a and the second bracket 120, and a pivot axial direction of the second connecting rod 130b and the first bracket 110 are parallel to each other. The first sliding portion 132 is rotatably connected to the first connecting rod 130a, and the second sliding portion 134 is rotatably connected to the second connecting rod 130b. An end of the pressing component 140 (the left end of the pressing component 140 in FIGS. 5 and 6) is connected to the first bracket 110, as mentioned above, and the other end of the pressing component 140 (the right end of the pressing component 140 in FIGS. 5 and 6) is connected to the second shaft 130d. Through the connection of the above components of the pivot assembly 130, the pivot assembly 130 can operate as shown in FIGS. 4A to 4C.

In view of the foregoing, in the hinge module according to the disclosure, the first sliding portion of the pivot assembly slides along the first sliding slot of the first bracket with the first bracket and the second bracket rotating relative to each other. In this way, different pressing forces can be applied to the first sliding portion through different positions of the pressing component in the moving path of the first sliding portion, such that the torsional force provided by the hinge module is not a constant value and the effects of both the convenience of operation and structural stability are achieved. In addition, the locking force applied to the pressing component by the lock assembly is adjustable to change the pressing force applied to the first sliding portion by the pressing component. In this way, the torsional force of the hinge module is corrected to make the second body more user-friendly when the user opens up or shuts the second body.

It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
